SunEarth ThermoRay 80-Gallon Solar Water Heater System
SunEarth ThermoRay 80-Gallon Solar Water Heater System Review
The SunEarth ThermoRay 80-Gallon Solar Water Heater System is a complete residential solar water heating package — collector + storage tank + pump + controller. Designed for full-package installation rather than component-by-component sourcing.
Specs: 80-gallon storage tank with internal heat exchanger, 40 sq ft SunEarth collector, circulation pump, differential controller. SRCC certified system rating.
SunEarth's complete-system positioning differentiates from collector-only purchases — easier specification and warranty (single-source) for homeowners new to solar thermal. The 80-gallon storage supports typical residential demand with sun-fraction 60-80% in good climates.
About $6,500-$8,500 installed depending on regional install costs. Federal Section 25D credit (30% of install) reduces net cost meaningfully.
Right buyer: solar water heating install in regions with strong sun exposure (California, Arizona, Hawaii) wanting complete-package sourcing.
- 10-year warranty — solid above-average coverage for this class
- Large 80-gallon reserve — comfortably serves 5+ person households in peak-use periods
- Professional installation required — gas/venting/electrical work adds $500–1,500 to unit cost
